IMPROVEMENT IN LEATHER STUFFING AND FULLING MACHINES.

' Specification forming part of Letters Patent No. 177,576., dated May 16, 1576; application filed April 19, 1876.

resident of the city of St. Louis, State of Missouri, have invented a new and useful Improvement in Leather Stuffing and Fulling Machines, of which the following is a full, clear, and exact description, reference being had to the annexed drawing, making part of this specification, in which Figure l-is a plan of the invention Fig. 2, a side elevation; Fig. 3, a vertical cross-section on the line at m, Fig. 1; Fig. 4, a similar section on the line y y, Fig. 1; and Figs. 5 and 6, a sideand top view, respectively, of the follower- Like letters indicate like parts. The present invention relates to an improved construction for stuffing and fulling leather,

' the principal feature of which is a trough or cylinder arranged horizontally, and containing the stuffing compound in a liquid state, and in which the leather is worked by being attaehed to a horizontal shaft journaled in the ends of the trough, and having a reciprocating rotary movement therein. Another feature of the invention is the provision for warming the trough. It further relates to the means employed. in reversing the movement of the trough-shaft. It also relates to the interior construction of the trough, by means whereof .the leather is more effectually manipulated,

and brought in contact with the stufling.

Referring to the annexed drawing, A represents a trough, preferably of a cylindrical form, and of a size sufficient toreceive leather in the condition in which it is usually dressed. It is arranged horizontally, and issupported in any suitable manner. Itis,preferably, made in two parts, a lower part, a, which is the trough proper, and an upper part or cover, a. B represents a shaft arranged horizontally in the trough, and journaled in the ends thereof, and, preferably, as shown. The shaft is provided with a clamp; b, by means of which the piece of leather is fastened to the shaft. (J O, &c., represent ribs arranged longitudinally in the shell of the trough, and also in the cover. They form projections for the leather to rub against as it is carried around by the shaft, and thus facilitate the operation. They are, preferably, removable, in order that when worn out these partsrcan be easily renewed; and they are, preferably, made of wood, or a material unaffected by the tannin in the leather. The cover is hinged to the trough, and, after the leather is attached to the shaft, it can be closed. There are openings D D, 8rd, in the cover, through which the operation can be viewed, and through'them, also, the stuffing can be introduced. If desired, the trough can be made in onepart, and in such case the sides ,of the trough can be carried up higherv than "as when a cover is used, and the leathercan be inserted through the opening in the top, and where the cover now is. E represents a follower, movable on the shaft B, and held at any point by means of the screws 0 e, &c., and by means of the follower the leather can be pressed laterally. F represents a steampipe arranged beneath the trough, by means of which heat is supplied to the bottom of the trough, and to keep the stuffing ingredients,

of the system of mechanism shown at theleft in Figs. 1 and 2, and as follows: Let a belt be running on a pulley, J, which is arranged on a shaft, I, upon the. inner end of which is a pinion, H, engaging witha spur-wheel, G, upon an extension of the shaft B. This causes the shaft B to revolve a certain number, say, eight or ten times, and sufficiently to wrap the leather entirely around the shaft. At this time a nut, O, which is arranged on a screw-shaft. N, and which shaft is provided with a pinion, P, engaging with the wheel-Gr, has been caused to travel on the shaft N sufficiently to move a weighted lever, Q, that is pivoted in a standard, q, and in moving it to move a slide, R, and, by means of the guides r r to shift the belt onto a pulley, J. The motion is then transmitted through the shaft S, gear-wheels- K K, shaft L, and pinion M, tothe wheel G, causing the latter to rotate in the opposite direction, and until the lever Q has been reversed, when the above movement is repeated, and so on. To operate the lever the nut O is provided with a projection, 0, which passes between the forked end q q of the lever. As the 2 name nut moves, the projection strikes first one fork and then the other, and, moving the lever in this manner, the leather is thoroughly Worked and kneaded in the stuffing, and the operation is effected in a much shorter time than heretofore has been necessary. By means of the device for warming the trough, the trough and itscontents are kept in such a condition as to greatly facilitate the operation.

What I claim is-- 1. The combination of the trough A, shaft 13, and clamp 1), arranged and operating substantially as described.

2. The combination of the trough a, cover a, shaft B, and clamp 1), arranged and operating substantially as described.

3. The combination of the trough A, shaft B, follower E, and screws 0 e, &c., substantially as described.

4. The combination of the trough a and pipe F, arranged outside and independent of the trough, substantially as and for the purpose set forth.

5. The combination of the trough A, shaft B, wheel Gr, pinion H, shaft I, and pulley J, substantially as described.

6. The combination of the lever Q, forks q q, slide R, nut 0, and projection 0, substantially as described.

7. The combination of the wheel G, pinion P, shaft N, nut 0, projection 0, lever Q, and forks q q, substantially as described.

8. Thecombination ofthe cylinder A, shaft B, clamp b, and ribs 0 O, 860-, substantially as described.
